These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Gretel And Hansel
Crowning Moment of Heartwarming: Despite (or perhaps because of) the extremely cynical nature of the game, Gretel being reunited with Hansel certainly counts.
To a lesser extent, when you give Rufus his hat back.
Good Bad Bugs: In the second game, it is possible, through a bug, to get both the Wolf-Slaying Arrow and the Bone by taking one, leaving, going back into the cave, and lighting the other torch. This will cause the game to freeze, as it doesn't know how to react since the Eldritch Abomination is still too frozen to attack you, even though you have both items. Simply reload the game to continue with both items. However, when encountering the wolf, you'll only use the arrow.
The face stealers, especially since the situation seems to be very much an And I Must Scream situation, it's satisfying to save Rufus, when you save Emma, she dies, because that's how it was originally supposed to be.
If you find the key to the room of the parents... Don't enter. Just don't.
The tree creature's dinner party in the second game. The twisted music, the dead girl still stuck in her chair, guests sprouting branches from their faces and the tree creature serving human flesh.
Tear Jerker: Emma's part of the forest. You know it's going to be something bad when you first arrive, even without the glasses, because the music stops and is replaced by the sound of a crying woman. When you do get the glasses, though, you get to watch Emma's life with her supposed husband... including how he attacked her with an axe and left her to die.
